In the beginning, Anna Paquin's Rogue was set to appear in the new X-Men movie, X-Men: Days Of Future Past. Then director Bryan Singer said her future-set scene had been cut, and fans - well, some fans - were in uproar. Now, after appearing on a cover of Empire and admitting she was disappointed not to make it into the film... she's back in.

Buzzfeed spotted that her name appears in the credits at the end of the latest X-Men: Days Of Future Past trailer, and after contacting Fox to check whether she might be a mutant once more, news has arrived that she will be, albeit briefly. “Essentially, [it’s] a cameo,” were the words the representative used.

Sounds like a blink-and-you'll-miss-it affair - no pun intended - but it should please her legion of admirers (and possibly peeve folk who didn't like her interpretation of the much-loved comic-book character).

To fill you in, Days Of Future Past finds Professor X (Patrick Stewart), Magneto (Ian McKellen), Wolverine (Hugh Jackman) and the current X-team confronting a dark alternate future where mutants are an endangered species, tracked down, imprisoned or killed thanks to Bolivar Trask (Peter Dinklage)’s Sentinel program and an overwhelming level of distrust from regular humans.

They boldly plan to send Wolverine’s consciousness back in time to the First Class era (or a few years after we last met those versions of the characters) to convince the younger Professor X (James McAvoy), Magneto (Michael Fassbender) and the rest to work together to stop the threat at its source.

With Ellen Page, Daniel Cudmore, Halle Berry, Shawn Ashmore and others back, including most of the First Class cast, Days Of Future Past is out on May 22.
